UND ERFRAMING FOR RAILWAY ROLLING-STOCK.

SPECIFICATION forming part of Letters Patent No. 678,958, dated July 23,1901.

Application filed November 23, 1900. Serial No. 37,452. (No model.)

To to whom it may concern.-

Be it known that I, GEORGE I. KING, 3. citizen of the United States,residing at the city of Detroit, in the county of Wayne, State ofMichigan, have invented a certain new and useful Improvement inUnderframing for Railway Rolling-Stock, of which the following is afull,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure 1 is a plan View of my improved underframing, the floorbeing broken away to more clearly show the framing of one end of thecar. Fig. 2 is a side elevational view of my improved underframing asadapted to a flat-oar. Fig. 3 is a sectional View on line 3 3, Fig. 1.Fig. at is a sectional view on line 4: 4, Fig. 1; and Fig. 5 is asectional view on line 5 5, Fig. 1.

This invention relates to a new and useful improvement in under-framingfor railway rolling-stock, the object being to construct a simple andstrong underframing made up of pressed or structural shapes, the wholebeing rigidly secured together by rivets or other suitable fasteningdevices.

With this object in View the invention consists in the construction,arrangement, and combination of the several parts, all as willhereinafterbe described and afterward point ed out in the claims.

In the drawings, A indicates the center sills, which are preferablydeepest at the middle portion of the car and provided at their upper andlower edges with flanges which are presented outwardly.

B indicates the side sills, which are in substantially all respectssimilar to the center sills, with the exception that I prefer to havethe flanges of the side sills presented in wardly. In order tostrengthen the center sills, I prefer to employ a cover-plate O, whichmay extend throughout the length thereof from bolster to bolster but inordinary practice it is only necessary to cover a portion of thislength. A bottom cover-plate D may also be provided along the deepestportions of the center sills for adding strength to the structure. 7

E indicates floor-beams supported by the center and side sills throughthe instrumentality of suitable angle or corner connection plates, saidbeams carrying wooden nailingstrips or longitudinal intermediatefloor-sills F, to which the floor-boards G may be secured.

Instead of using a removable body-transom in connection with my improvedunderframing I prefer to arrange an equivalent for such a structure,which equivalent is in-the nature of a body-transom, but is built in theunderframing and forms a material part thereof.

H indicates a cover-plate, which preferably extends entirely across theunderframing, said cover-plate being riveted to the top flanges of theside sills.

I indicates a bottom cover-plate, which preferably extends entirelyacross the underframing and is riveted at its ends to the bottom flangesof the side sills. Between these coverplates are webs J, either composedof structural rolled forms or pressed forms and angles'or sheared platesand angles, the Webs shown in the drawings being I-shaped incrosssection, their top and bottom flanges being riveted to the top andbottom cover-plates be' fore described.

Corner-connection angles or plates j are employed to secure the webs tothe center sills, and corner-connection angles or plates j are employedto secure the outer ends of the webs to the side sill. Where websI-shaped in cross-section are employed, top and bottom flanges are cutaway to accommodate the flanges of the center and side sills, as shownin Fig. 4.

K indicates a casting arranged between the center sills and on top ofthe bottom coverplate,and L indicates a center bearing riveted t0 thebottom cover-plate and to the casting K.

M indicates the side bearings, which are riveted'to the bottomcover-plate and the bottom flanges of the web-plate J.

N indicates the end sill, which may be composed of structural members,said end sill in the drawings being illustrated as a casting, to theinner face of which the center and side sills are secured by theemployment of suitable corner angles or connection plates.

Both the web-plates J and the end sills have secured to themstirrup-brackets f for supporting the longitudinal wooden sills F.

71 indicates connection-plates riveted to the top flanges of the sidesills, and n connection-plates riveted to said side-sill flanges and theend sills for the attachment of diagonal brace members N and N, whoseinner ends are riveted to the top cover-plate, as shown in Fig. 1.

The underframing above described may be used for various types of cars,the type shown in the accompanying drawings being that of the well-knownflat-car, which is provided with the usual stake-pockets, &c.

I am aware that minor changes in the arrangement, construction, andcombination of the several parts of my device can be made andsubstituted for those Herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby. Letters Patcut, is

1. In an underframing for cars, the combination with flanged metalliccenter and side sills of uniform depth near the ends, of atransversely-disposed top cover-plate continuous from side sill to sidesill and riveted to the top flanges thereof, a bottom coverplate alsocontinuous from side sill to side sill and riveted to the bottom flangesthereof, I-shaped web-plates adapted to lie flush with the upper andlower surfaces of the sills riveted to the cover-plates, and cornerconnections for securing the ends of said web-plates to the center andside sills, respectively, substantially as described.

2. In an underframing for cars, the combination with center sills whoseflanges are presented outwardly, and side sills whose flanges arepresented inwardly, said sills being of uniform depth near the ends ofthe car, of transversely-disposed top and bottom coverplates continuousfrom side sill to side sill, the top plate being riveted at its ends tothe upper flanges of the side sills, and the bottom plate being rivetedto the lower flanges thereof, commercially-rolled I-shaped Web-platesarranged between said cover-plates and extending between the side sillsand their nearest center sill, the top and bottom flanges of saidweb-plates being removed at the ends of the plates to accommodate theflanges of the side and center sills, whereby the top and bottom facesof said side and center sill I flanges and web-plate flanges are flushfor the continuous attachment of the cover-plates, connection-platesriveted to the reduced ends of the webplates, and to the side and centersills, a casting between the center sills and in the transverse plane ofsaid web-plates, and center and side'bearings secured to the bottomcover plate; substantially as described.

3. 'In an underframing for cars, the combination with center and sidesills having their flanges presented toward each other, respectively,said sills being deepest at their middle portions, the shallow endsbeing of uniform depth for some distance from the end I of the car, endsills to which the ends of said center and side sills are attached,floor-beams supported by the center and side sills, an

elongated cover-plate for tying the center sills together at the centerof the car, commerci'ally-rolled I-sbaped web-plates correspending indepth to the shallow ends of the center and side sills, and arrangedtherebe tween, the top and bottom flanges of said web-plates being cutaway to accommodate the flanges of the center and side sills, a fillerbetween the center sills in the transverse plane of the web-plates,connection-plates riveted to the web-plates and to the side and centersills, and top and bottom cover-plates riveted to the flanges of theweb-plates and tothe center sills; substantially as described.

4:. The combination with side and center sills, of floor-beams supportedthereby, transversely-disposed top and bottom cover-plates, web-platesinterposed between said coverplates, an end sill, stirrups on said endsill and web-plates, and longitudinally-disposed wooden sills mounted insaid stirrups and supported by said floor-beams substantially asdescribed.

5. In an nnderframing for cars, the combination with center and sidesills consisting of metallic beams continuous longitudinally of the carand made deepest at their middle portions, bod y-bolsters and end sillsfor tying the center and side sills together, an elongated cover-platerunning lengthwise of the car secured to the center sills, and a bottomcover-plate extending throughout the deeper portions of the said centersills and secured thereto, substantially as described.

In testimony whereof I hereunto aftix my signature, in the presence oftwo witnesses, this 21st day of November, 1900.

GEORGE I. KING.
